Does WFPB resemble any traditional food system practiced anywhere in the world? Yes. WFPB guidelines overlap with the Blue Zones Diet and Nature Cure guidelines. However, the number of people who follow these two diets are so few!
WFPB guidelines overlap with Veganism to the extent that it often gets confused with Veganism. However, the two are different. Turns out that the vast majority of Vegans are 'ethical vegans' who incorporate one half of Whole Food Plant-Based diligently into their personal lives: the "Plant-Based" portion. Most ethical vegans ignore the "Whole Food" part; their food plates often have processed foods, stimulants (alcohol, coffee) and extracts (sugar, oil).
The surging popularity of Veganism in the world has made life simpler for those who follow Whole Food Plant-Based guidelines. At least plant-based options are now available in many restaurants. Culturally, many of our friends and family members understand the idea of 'No Animal Products'.
